Code Classification

  • Endocrine, nutritional and metabolic diseases
    (E00–E89)
    • Metabolic disorders
      (E70-E88)
      • Other disorders of fluid, electrolyte and acid-base balance
        (E87)

E87 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of other disorders of fluid, electrolyte and acid-base balance. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Other disorders of fluid, electrolyte and acid-base balance

Non-specific codes like E87 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for other disorders of fluid, electrolyte and acid-base balance:

  • Use E87.0 for Hyperosmolality and hypernatremia - BILLABLE CODE

  • Use E87.1 for Hypo-osmolality and hyponatremia - BILLABLE CODE

  • E87.2 for Acidosis - NON-BILLABLE CODE

  • Use E87.20 for Acidosis, unspecified - BILLABLE CODE

  • Use E87.21 for Acute metabolic acidosis - BILLABLE CODE

  • Use E87.22 for Chronic metabolic acidosis - BILLABLE CODE

  • Use E87.29 for Other acidosis - BILLABLE CODE

  • Use E87.3 for Alkalosis - BILLABLE CODE

  • Use E87.4 for Mixed disorder of acid-base balance - BILLABLE CODE

  • Use E87.5 for Hyperkalemia - BILLABLE CODE

  • Use E87.6 for Hypokalemia - BILLABLE CODE

  • E87.7 for Fluid overload - NON-BILLABLE CODE

  • Use E87.70 for Fluid overload, unspecified - BILLABLE CODE

  • Use E87.71 for Transfusion associated circulatory overload - BILLABLE CODE

  • Use E87.79 for Other fluid overload - BILLABLE CODE

  • Use E87.8 for Other disorders of electrolyte and fluid balance, not elsewhere classified - BILLABLE CODE

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • diabetes insipidus E23.2
  • electrolyte imbalance associated with hyperemesis gravidarum O21.1
  • electrolyte imbalance following ectopic or molar pregnancy O08.5
  • familial periodic paralysis G72.3
  • metabolic acidemia in newborn, unspecified P19.9

Patient Education


Fluid and Electrolyte Balance

Electrolytes are minerals in your body that have an electric charge. They are in your blood, urine, tissues, and other body fluids. Electrolytes are important because they help:

  • Balance the amount of water in your body
  • Balance your body's acid/base (pH) level
  • Move nutrients into your cells
  • Move wastes out of your cells
  • Make sure that your nerves, muscles, the heart, and the brain work the way they should

Sodium, calcium, potassium, chloride, phosphate, and magnesium are all electrolytes. You get them from the foods you eat and the fluids you drink.

The levels of electrolytes in your body can become too low or too high. This can happen when the amount of water in your body changes. The amount of water that you take in should equal the amount you lose. If something upsets this balance, you may have too little water (dehydration) or too much water (overhydration). Some medicines, vomiting, diarrhea, sweating, and liver or kidney problems can all upset your water balance.

Treatment helps you to manage the imbalance. It also involves identifying and treating what caused the imbalance.
